While the last module of this course is very interesting and kept with the specialization, the first 5 modules are a waste of time for the most part. Why would I want to learn about AT&T for two weeks? The amount of useful concepts introduced in the first 5 modules won't take more than 15 minutes if unnecessary things were removed.

This could probably be better broken into two one week courses "History of Phone Technology" and "Intro to IoT". Many reviewers say they bail out in first few lectures because content seems too far removed from IoT. I enjoyed the last few lectures with examples of IoT, but could have skipped the rest.

Th content was fine but the Q&A was not on point, some were badly timed and some were not correctly phrased and evaluated. Got to know a lot of information on telecommunications journey, and a lot on its rich history of triumphs and pitfalls. Great content.

pace is slow. so many video in pieces, and lecturers keep saying like" we will look into more details later" or introduction again and again. I am studying module 2 now, all small lectures like 1 min or 2 mins, which is very shattered, repetitive and annoying.

The quiz questions should reviewed again and place at appropriate checkpoints, corresponding to content covered. It will also be good to spread out the content into different weeks and modules to ensure that the workload is more manageable.

In itself interesting content, structure was difficult to follow and the history - in my humble view - was going back too far into the past whereas more recent developments where only touched at the surface, quality of slides was poor.

This course helped me in getting introduced to the IOT space, it is very basic/preliminary in nature but helps in setting up stage/ context for acquiring more knowledge and hands on next sessions of the certification.

Content is interesting however there seems to be a lot of quizzes with inappropriate questions that are not taught. This is better in module 6 where the questions were answerable by viewing the teaching materials.

The teaching has been concise and to the point which is good but not so good for a few difficult topics. Also I've been experiencing video lag and audio stuttering while streaming the videos so there's that.

You must provide some materials because it some time get very irritating to answer your quizzes.I just wanted to know that why you guys wanted us to know about the history of AT&T and Bell labs.

Great instructors.

Lots of historical references and terminology. I would prefer more details about how stuff actually work - in simple layman's terms.

Looking forward to the second course.

The quizzes were very demotivating for me as most of the questions were not covered in the lectures at all. That being said, the lecturer was lively and taught with enthusiasm.

This course is more of a history type of course which bores the learners. Course should be more of technological knowledge rather than the history of the technology.

It is informative, but there are many basics that were not covered well & there was a lot of information that was not that interesting (like too much history)

A lot of background information, most of which I was unfamiliar with. Kind of dragged on, but I think it'll ultimately be helpful in the specialization.

Course content is good and gives a good historical perspective of communication systems, but quizzes are mostly irrelevant and in some cases incorrect.

Quiz questions were very often unrelated or not found in the video lecture content. The early half of this course largely pertains to the History of IoT

i feel this course start is somewhat bored because of teaching is not practical based and better follow udacity website tech for teaching interactively

The course is fine, but I would give the certificate out for free and charge for the ones that follow in the specialization as an incentive to enroll.

the content is inspiring but some of the content in quizzes are not stated in the lectures, making a hard time to search and check for the answers.

In most part the quizzes were asking topics not mentioned in videos or didn't give an extra lecture to make a read a prepare the quiz

Interesting but very introductory. Don't expect to really learn something significant. Easy course. Accent is hard to understand.

Introductory, not completely relevant to my goals, could be ommitted. Nevertheless, I enjoyed the delivery of the instructor.

Not much useful if you want to learn about IOT but helpful if you want to learn historical development that lead to IOT

Good course and great content, but the quizzes are tad irrelevant with the content. and have a lot in extra to answer.
